What are the advantages and disadvantages of intangible assets?

Intangible assets, such as patents, trademarks, and goodwill, offer several advantages, including the potential for high returns, competitive differentiation, and the ability to enhance a company's market value. However, they also come with disadvantages, such as difficulty in valuation, potential for obsolescence, and challenges in legal protection. Furthermore, intangible assets can be less tangible in terms of liquidity, making it harder to convert them into cash compared to physical assets.
